Ciklum vs Tallium: overview

Ciklum

Ciklum's legal headquarters moved from Kyiv to London some years after its 2002 founding, which is unusual on a UK-facing list: most outsourcing companies serving British clients are headquartered elsewhere and simply sell into the UK market. Its roughly 3,900-person team still delivers primarily from Ukraine, spanning full-lifecycle product engineering across cloud, data, and digital work for enterprise clients. That London incorporation gives UK buyers a domestic contracting entity, something several peers on this list, however strong their engineering, simply cannot offer.

Tallium

Every other company on this UK-facing list quotes engagements privately; Tallium, founded in Kyiv in 2012, simply posts its rate on GoodFirms instead: $25-$49 per hour, backed by a 5.0-star rating across more than 40 verified reviews. That transparency makes genuine cost comparison possible before a first call, a real advantage for a UK buyer sizing up a budget before committing to a discovery process. Its boutique scale suits single-team engagements rather than the multi-hundred-person programs a firm like SoftServe or Ciklum can staff.
